To all whom it may conocm: Be it known that I, WALTER I-I. Come,

a citizen'jof the United States, and-a res1-.

dent ofthe city of Troy, in the county of Miami'and State of Ohio, have inventedcertain new and useful Improvements 1n Pipe-Couplings for Irrigatin'g Systems,jof' which the follo'winglis a full,'clear, and exact description, reference being had to the accompanying drawings, forming part of this specification. a

In providing a coupling for'the p1pes m an irrigating system where there are a series of nozzles in each pipe and the .pipes are rotatedjto swing the nozzles in an arc of say one I hundred and twenty degrees, there mustbe rigidity ofconnection so that there-'is-no play in the joint. It is also req-'. uisite-to have a non-leaking 'fit and hlghly desirable to havethe coupling quick and sure.

With the object of obtaining such a coupling, I have provided in my coupling a male and a female part, these parts to be squared, and other devices, as will be herein'after specifically pointed out and claimed. In, the drawings,

. Figure is the coupling piece for a pipe havingthe female squared end, shown in vertical section.

Fig. 2 is thesecuring sleeve in vertical section.

Fig. 3 is a vertical sectionoflthe coupling I 2 piece for the pipe to be coupled, havingthe fied coupling.

squared male part. p

Fig. 4 is a side elevation of the coupling complete. Figs. 5 and 6 are end elevations of a mod1- 'The coupling plece 1 is designedfto. be

screwed on .a pipe, and is provided with afiange 2 to be used in holding the securing sleeve in the ordinary manner. The mouth the pipe to be coupled.

of. this piece is extended and squared as be.- fore mentioned and forms a square .stud 3 to fit a squared female part on the end of The securing sleeve 4: hasa flange -5 to ride over the flange. 2, and is provided with a handle 6 for operating. The sleeve: is screwthreaded at 7 to engage the other pipe end coupling'piece, which will be descrlbed.

' pipes.

i The sleeve and coupling piece 1 are inpermanently andv rigidly on the pipe .1 to which they aresecured.

The coupling'piece 8 for the pipe to be .coupled is. screwthreaded at its forward end '9, and its mouth is squared so as to form a square socket 10 adapted to-receive the square stud 3 a'lrea'dy described. A packing rmg 11 1s provided to rest against the shoulder formedby cutting away to form the square stud. p In making up the coupling,l the piece .1 1s soc et. This should be done so that the nozzle 12 in the pip'e'8 which is the coupled pipe, will lie on the same line as the i102 es 123 in the ipe 1 (Fig. 4:).

When t e stud s inserted i11' place,i

ushed in so that the stud lies; in its.

tended to remain permanently together, and

screwthreads of the coupling p1ece:8,andi I of the sleeve are lined up properlyso. that the sleeve can be quickly turned bvjmeans of its handle to securely clamp the coupling pieces together.

The imparting of revolving motion to the pipe 1 will then impart like motionto the pipe 8% The nozzles will be lined up correctly because the squaring of stud and socket will be in a like position with, regard to the nozzles on each p pe and the operator can line them up exactly when pushing in the. stud.

It is believed'that the structure and operation of my coupling are now fullyv pre-' sented- By a strict description of details it is not intended to limit the scope of the claims that follow. Obvious mechanical equivalents, such as diamond or pyramid shaped male and female parts are, of course, desired to be covered without being specifically noted herein. The coupling would be a valuable one for hose, also, as well as Another form of coupling piece which would parallel in some ways the one above shown and described, would be as follows (Figs. 5 and 6). Theends 8 and 1 would u not have any special kind of orifice, but would have for alining and rigid connec-- tion, sockets 14, 14, for the female piece 8, .and pins 15, 15, for the male piece 1. When the parts are'put together for coupling, the

pins will have to be inserted in the sockets, thereby accomplishing the same purpose .as the squared orifices more accurately but with less ease and with considerably less security.

. Having thusdescribed my invention, what I claim as new and desire to secure by Letters Patent, is

1. In an irrigating system, in combination with'a plurality of pipes, having a series of nozzles longitudinally therein, means for quick coupling said pipes so that the series of nozzles shall be in absolute line with each other, comprising interlocking members 'on the two pipes adapted to find their locking position when the nozzles are r perly alined, a sleeve revoluble onone pipe, and screwthreads on the other pipe'toengage threads on the sleeve.

2. In an irrigating system, in combination with a plurality of pipes, having a series of nozzles longitudinally therein, means for quick 'coupling'said pipes so that the series of nozzles shall be in absolute line with each other, comprising interlocking members on the two pipes adapted to find their locking position when the nozzles are properly alined, and means for drawing and holding together said interlocking members.
